The term is used primarily in reference to trees and shrubs, in contrast with those that are evergreen.. It is pronounced dih-SIJ-oo-uhs. To remember what deciduous means, try relating it to the word, decadent..
viscosity. n, pl-ties. 1. the state or property of being viscous. 2. (General Physics) physics. a. the extent to which a fluid resists a tendency to flow. b. Also called: absolute viscosity a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared.
Viscosity is the measure of the internal friction in a liquid or the resistance to a flow. Low viscosity fluids flow easily (water, alcohol); High viscosity fluids pour slowly (molasses, cold honey, etc.).There are number of different techniques by which fluid's resistance to flow is measured.iscosity is the measure of the internal friction in a liquid or the resistance to a flow.
